Hinge for an eyeglasses frame

Abstract

A frame of eyeglasses lens is described comprising a ring, to accommodate the perimeter of the lens, with two free clampable ends for closing the ring and tightening it around a lens. a temple rod ( 50 ) and a hinge for the rod ( 50 ) formed by a hooked or curved portion, comprised at an end of the rod ( 50 ), configured to slidingly grip onto the outer surface of the first member.

1 . Frame of eyeglasses lens comprising
 a ring, to accommodate the perimeter of the lens, having an end consisting of two free clampable ends for closing the ring and tightening it around a lens.   a first and second member which can be connected to each other to tighten said free ends, wherein the first member is equipped with
 a slot in which to insert said ends and 
 a surface access shaped so that through it the second member, by only a linear translation along an axis can be inserted inside the first member to reach a position in which it cooperates with said ends to lock the latter inside the slot; 
   a temple rods and   a hinge for the rod formed by a hooked or curved portion, comprised at an end of the rod , configured to slidingly grip onto the outer surface of the first member.   
     
     
         2 . Frame according to  claim 1 , wherein said access comprises threaded walls on which a surface thread provided on the second member can be screwed to perform said linear translation of the second element, the second element being a screw or a threaded dowel. 
     
     
         3 . Frame according to  claim 1 , wherein the second member is configured
 in such a way that, following said only linear translation along said axis, it divaricates said two ends to push them in opposite directions against the inner walls of the first member, or   so that, following said only linear translation along said axis, it pushes on said two ends to push them against the inner walls of the first element.   
     
     
         4 . Frame according to  claim 1 , wherein the first member comprises a base from which two parts separated by said slot protrude cantilevered, wherein the slot is delimited by two walls parallel to each other of the two parts, said access being placed at an intermediate point of the two parts separated by said slot and extending inside the first element parallel to said parallel walls towards the center of the first element. 
     
     
         5 . Frame according to  claim 1 , wherein the first member comprises surface facets to give the rod a snap movement when it rotates dragging on the first member. 
     
     
         6 . Frame according to  claim 5 , wherein the facets in the first member are in correspondence with said two parts separated by said slot, wherein the first element comprises a polygonal-base prism divided in half by the slot. 
     
     
         7 . Frame according to  claim 1 , wherein said two parts separated by said slot comprise on the external lateral surface thereof a smooth band that runs all around the first element. 
     
     
         8 . Frame according to  claim 9 , wherein the smooth band and the polygonal-base prism are divided by two circular edges protruding from the external lateral surface of said two separate parts. 
     
     
         9 . Frame according to  claim 1 , wherein the rod comprises a first and second prong so curved that each has a concavity facing the other, thereby forming altogether a structure for rotatably connecting in a sliding manner to the external surface of the first element. 
     
     
         10 . Frame according to  claim 9 , wherein the rod comprises three prongs;
 a first prong to slide on the band between the two protruding circular edges, and   a second and third prong having the same curvature to slide on the facets, the first prong being curved so as to present a concavity facing the curvatures of the second and third prongs.   
     
     
         11 . Frame according to  claim 1 , wherein the free clampable ends are configured so that, when they are attached to each other, they fit together to form an overall pass-through opening,
 a free end of a prong, in particular said first prong, having dimensions such that it can pass through the pass-through opening when the rod rotates with respect to the first element.   
     
     
         12 . Frame according to claim  1 , wherein one or more prongs are configured to abut against the end of the ring when the angle between the rod and the front piece comprising the ring is greater than 90 degrees, so as to create an end-of-travel position for the maximum opening angular rotation of the rod. 
     
     
         13 . Frame according to  claim 2 , wherein the second member is configured
 in such a way that, following said only linear translation along said axis, it divaricates said two ends to push them in opposite directions against the inner walls of the first member, or   so that, following said only linear translation along said axis, it pushes on said two ends to push them against the inner walls of the first element.   
     
     
         14 . Frame according to  claim 2 , wherein the first member comprises a base from which two parts separated by said slot protrude cantilevered, wherein the slot is delimited by two walls parallel to each other of the two parts, said access being placed at an intermediate point of the two parts separated by said slot and extending inside the first element parallel to said parallel walls towards the center of the first element. 
     
     
         15 . Frame according to  claim 5 , wherein said two parts separated by said slot comprise on the external lateral surface thereof a smooth band that runs all around the first element 
     
     
         16 . Frame according to  claim 15 , wherein the smooth band and the polygonal-base prism are divided by two circular edges protruding from the external lateral surface of said two separate parts.
